Types of thyroid diseases The two most common types of thyroid disorders are hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid). Hypothyroidism occurs when the thyroid gland does not produce enough thyroid hormones. Symptoms include weight gain, fatigue, dry skin, hair loss, among others. An overactive thyroid gland could lead to hyperthyroidism. This happens when thyroid gland produces an excess of thyroid hormones. Common symptoms of the condition are weight loss, increase in appetite, increased heartbeat, anxiety, irritability, and heat intolerance. In Hashimoto's thyroiditis, the immune system attacks and damages the thyroid gland, leading to hypothyroidism. In case of Graves ' disease, thyroid gland produces excessive amounts of hormones, resulting in hyperthyroidism.
